[Show abstract][Hide abstract] ABSTRACT: Obesity has been associated with worse postoperative outcomes. No data are available regarding short-term results after liver resection (LR). The aim of this study was to analyse outcomes in obese patients (body mass index [BMI] > 30 kg/m(2) ) undergoing LR.
85 consecutive obese patients undergoing LR between 1998 and 2008 were matched on a ratio of 1:2 with 170 non-obese patients. Matching criteria were diagnosis, ASA score, METAVIR fibrosis score, extent of LR, and Child-Pugh score in patients with cirrhosis.
Operative time, blood loss and blood transfusions were similar in the two groups. Mortality was 2.4% in both groups. Morbidity was significantly higher in the obese group (32.9% vs. 21.2%; P= 0.041). However, only grade II morbidity was increased in obese patients (14.1% vs. 1.8%; P < 0.001) and this was mainly related to abdominal wall complications (8.2% vs. 2.4%; P= 0.046). No differences were encountered in terms of grade III or IV morbidity. The same results were observed in major LR and cirrhotic patients. When patients were stratified by BMI (<20, 20-25, 25-30 and >30 kg/m(2) ), progressive increases in overall and infectious morbidity were observed (5.6%, 22.4%, 23.7%, 32.9%, and 5.6%, 11.8%, 14.5%, 18.8%, respectively). Rates of grade III and IV morbidity did not change.
Obese patients have increased postoperative morbidity after LR in comparison with non-obese patients, but this is mainly related to minor abdominal wall complications. Severe morbidity rates and mortality are similar to those in non-obese patients, even in cirrhosis or after major LR.
[Show abstract][Hide abstract] ABSTRACT: In patients with hepatocellular carcinoma (HCC), a previous liver resection (LR) may compromise subsequent liver transplantation (LT) by creating adhesions and increasing surgical difficulty. Initial laparoscopic LR (LLR) may reduce such technical consequences, but its effect on subsequent LT has not been reported. We report the operative results of LT after laparoscopic or open liver resection (OLR).
Twenty-four LT were performed, 12 following prior LLR and 12 following prior OLR. The LT was performed using preservation of the inferior vein cava. Indication for the LT was recurrent HCC in 19 cases (salvage LT), while five patients were listed for LT and underwent resection as a neoadjuvant procedure (bridge resection).
In the LLR group, absence of adhesions was associated with straightforward access to the liver in all cases. In the OLR group, 11 patients required long and hemorrhagic dissection. Median durations of the hepatectomy phase and whole LT were 2.5 and 6.2 h, and 4.5 and 8.3 h in the LLR and OLR groups, respectively (P < 0.05). Median blood loss was 1200 ml and 2300 ml in the LLR and OLR groups, respectively (P < 0.05). Median transfusions of hepatectomy phase and whole LT were 0 and 3 U, and 2 and 6 U, respectively (P < 0.05). There were no postoperative deaths.
In our study, LLR facilitated the LT procedure as compared with OLR in terms of reduced operative time, blood loss and transfusion requirements. We conclude that LLR should be preferred over OLR when feasible in potential transplant candidates.
